Description

The baudrate() routine returns the output speed of the terminal. The number
returned is in bits per second, for example 9600, and is an
integer.

With the erasechar() routine, the user's current erase character is returned.

The has_ic() routine is true if the terminal has insert- and delete-character
capabilities.

The has_il() routine is true if the terminal has insert- and delete-line
capabilities, or can simulate them using scrolling regions. This might be used
to determine if it would be appropriate to turn on physical scrolling
using scrollok().

With the killchar() routine, the user's current line kill character is returned.

The longname() routine returns a pointer to a static area containing a
verbose description of the current terminal. The maximum length of a verbose
description is 128 characters. It is defined only after the call to
initscr() or newterm(). The area is overwritten by each call to newterm() and
is not restored by set_term(), so the value should be saved between
calls to newterm() if longname() is going to be used with multiple
terminals.

If a given terminal doesn't support a video attribute that an application
program is trying to use, curses may substitute a different video attribute
for it. The termattrs() function returns a logical OR of all video
attributes supported by the terminal. This information is useful when a curses program
needs complete control over the appearance of the screen.

The termname() routine returns the value of the environment variable TERM (truncated
to 14 characters).

Return Values

longname() and termname() return NULL on error.

Routines that return an integer return ERR upon failure and an integer
value other than ERR upon successful completion.
